Over the past year, I’ve been writing a lot about scientists bringing back life from the distant past–including viruses, water fleas, and–theoretically–mammoths. For my “Matter” column this week in the New York Times, I report on another revival: moss that has started growing after spending 1500 years in a bank of permafrost. As more species return from the past, some scientists think it’s time to establish a new scientific field which they call “resurrection ecology.” In my column, I consider some of the things that resurrection ecologists can learn about the past and the future. Check it out. Continue reading “A Moss From King Arthur’s Court and the New Science of Resurrection Ecology” →

Jacob Landis writes, “I’m a graduate student at the University of Florida studying flower evolutionary development with a focus on plant/pollinator interactions. My ink represents the concept that I have been working on for almost 6 years now. This piece shows three species in the Phlox family. The red and white flowers are both part of the genus Ipomopsis and the blue/purple flower is in the closely related Polemonium. The pollinator of each flower is shown interacting with the flower. These interactions represent the concept of pollinator syndromes: certain features of the flower will attract certain pollinators. The long red tubular flowers attract hummingbirds, the white tubular flowers attract hawk moths, and the more open blue/purple flowers often attract bees.”

Life changes its surroundings. Beavers build dams that alter the course of rivers. Forests can feed thunderstorms with their moisture. And those changes can, in turn, create new habitats that allow for the evolution of new kinds of life. For my new “Matter” column in the New York Times, I discuss a hypothesis about a truly global act of bio-engineering that may have happened 700 million years ago. Sponges may have transformed the oceans, flushing them with oxygen. And thanks to that change, more complex animals were able to evolve. We may have sponges to thank for being here, in other words. You can read the whole thing here. Continue reading “Sponges: Planetary Engineers?” →
